Force: newtons, kilopond and pound-force

Force is measured in newtons. Kilopond and pound-force are older units tied to standard gravity and are still used in engineering and sport.

One newton accelerates a mass of 1 kg at 1 m/s². 1 kgf = 9.80665 N exactly (via standard gravity) and 1 lbf = 4.4482216152605 N. A kilopond is therefore not the same as one kilogram but roughly ten times the force; in German the unit is called Kilopond and abbreviated kp.
